Hi friendsI am doing Wold Bank MOOC course on Turn Down the heat: Why a 4 degree world should be avoided?

This page is created to display my final project for other course participants and evaluators.

Pl see and give your suggestions.

Sincerely,

In the artifact
given here, I tried to show that forest cover acts as umbrella to mother earth
to protect from CO2.Mother earth can
happily smile once forests take care of the emissions and carbon sequestration.Plant trees and save earth from climate
change.

Forests have
profound impact on climate change and climate change affects in turn forest
cover.However, annual deforestation is
estimated to release CO2 in more qualtity than annual emissions from transport system.
Forests act as carbon sinks and help in
absorbing CO2 in large quantities due to photosynthesis.Also, forest cover gives shade that reduce soil
temperature. The continued existence of
forests is important to prevent vicious cycle of rising temperatures –melting ice
cap –release of GHG-which leads to temperature rise.

As global
warming proceeds the forest ecosystems have to move to more suitable locations
as the existing locations become less suitable. It is estimated that with increased global
temperatures by 3 degree by 2100, the forest ecosystemes are likely to shift
500 km towards poles and 500 m to higher alitiudes.Intergovernmental Panel on Climate
Change (IPCC) concluded that suitable climate are projected to shift in
future and many tree species will not be able to change their geographic
distribution fast enough to keep up with such shifts. Often due to limited capability for the dispersal
of seeds of several tree species, the composition of the forest ecosytems is likely
to change.
